Use the "potentially visible objects" most. It does a pretty good job of calculating what is above you AND making sure it is at a visible angle to reflect sun to your gps coordinates.

If you use the ISS button it will tell you when the next potentially visible flyover is. Also, you can get real in depth with the settings and some of the other functions. It will let you actually plot out the area of the sky objects will eventually be moving through, mark them on your phone, then overlay it to the background your camera see's.
